PURPOSE:To aim at miniaturizing a car drive device, by organically combining a normally meshing type speed change gear, a differential gear unit and forward and backward movement change-over device. CONSTITUTION:Rotation from an engine 100 is transmitted to the drive pulley 56 of a V-belt type stepless speed change device 56. When a control lever is set at a forward first speed position, a shifter 76b is engaged with a small speed reducing gear 64b by means of a speed change drum 80 since a slider 66 is shifted to the right. Therefore, the rotation of an input shaft 54 is transmitted to a rear wheel axle 48 through a speed change gear shaft 52, the slider 66, the small speed reducing gear 64b, a large speed reducing gear 38b and a differential gear unit 36. Meanwhile at the Backward movement position, the slider 66 is returned to its neutral position while an idle gear 72 is moved to the position indicated by the phantom line, and the rotation of the input shaft 54 is transmitted to a gear 116, the idle gear 72 and a gear 118 integrally incorporated with the small speed reducing gear 64a to rotate the large speed reducing gear 38a and the rear wheel axle 48 in the backward direction. |
